Shaping of the world

I believe in good and bad, and right from wrong. It is true that shaping is a way that most people look at the world, as so do I. At the same time I also think that the idea of seperating good and bad is very closed minded, because when you think about it what necesirally is right and what is wrong? Grendels view of the world and shaping causes him to be angry and bitter, a way most people dont want to live. If doing one wrong thing in your lifetime causes you to be categorized as "bad" you could be missing out on what someone has to offer. Not being open to the fact that someone can reedem themself causes people to be stuck up and regretful. People deserve second chances so who am I or anyone for that matter to label someone good or bad? Shaping is true but also a very broad way of thinking and allthough some people live by it, everyone deciphers it in their own personal way that makes sense to ourselves.A part of me seperates the good from bad, but at the same time im not quite sure how to define either one. To live a life  believing someone who has once done bad is forever bad isnt living at all. We all make mistakes in this lifetime but its how we grow from it and take that experience that makes us the people that we are. I have always supported forgiveness and looking past things people have done that i dont necessarily agree with, so who am i to distinguish right from wrong?
